3 Claims.

This invention relates to supporting brackets for horizontal cylindrical vessels and is an improved construction of the bracket disclosed in Figure 1 is a side elevational view of a longi-- tudinal cylindrical vessel embodying the-present invention.

Fig. 2 is a transverse sectional view of the vessel shown'in Figure 1;

Fig. 3 is an elevational view of one end of the vessel viewed from the bottom in Figure l; and

Fig. 4 is a perspective view of a portion of the vessel showing the bracket.

In a vitreous enamel lined vessel, to be used for the storage of beer or other liquids afiected by contact with metal, it is important that the lining remain intact and that therefore no localized deflection or strain in the wall occur.

In practice it has been found that the least deflection of the vessel wall is obtained by supporting thevessel on four brackets arranged two at each head, as illustrated in the drawing.

Referring to the drawing, a horizontally disposed vitreous enamel lined vessel l0 has a cylindrical body portion II and dished heads l2 and I3. Heads l2 and I3 are secured to the'body portion H by welds l4 and I5 respectively.

Each bracket l6 comprises a substantially triangular fin plate l| edge-welded to the lower portion of the vessel head along the circumferential line of the so-called knee or knuckle of said head and having its outer edge in a vertical plane tangential to the vessel wall. A stiffening flange I8 is provided on the outer edge of the fin plate. A foot plate I9 is welded to the outer portion of the lower edge of fin l1 and to flange l8. .A gusset plate 20 is welded to each side of the fin l1 and to the top of foot plate l9.

A brace plate 2| is welded to the inner end-edge of foot l9 and is angularly disposed to engage the cylindrical wall of the vessel in a zone removed from the plate IT. The outer edge of the brace is approximately diagonally tangential to the cylindrical wall and the inner edge is cut away at its upper end to form a curve complementary to the curve of the wall it engages. The brace 2| is secured to the wall along itscurvedengaging edge by the weld 22. A stiffening flange 23 5 is welded to the upper face of the brace 2|. By securing the brace to the vessel as described the vessel wall provides an arched area which resists deflection.

As explained in the above mentioned patent the 1 brackets'must not only support the vessel under load in use without damage to the vessel, but must support the vessel during its period of heating for the purpose of fusing the enamel linin during manufacture. I 15 By welding the bracket me bers to the vessel wall in edgewise relation and by employing members of approximately the same thickness as that of the vessel wall, the heat for fusing the enamel is permitted to uniformly heat the vessel wall and 20 thereby prevent differences in temperature due to heat conduction to and from the vessel by the brackets.

The brace 2| supports fin l'l against bending by carrying a support back into the vessel wall where 26 the brace engages the wall in a diagonal circumferential line on an arched portion which resists deflection.

The improved brackets, as aboveexplained, permit the uniform firing of a vitreous enamel lin- 80 -ing in a vessel and the subsequent cooling of the vessel without injury to the enamel. The brackets also properly support the finished vessel in filled condition and protect it against excessive deflection and consequent injury to itself or its 35 vitreous enamel lining.

Various embodiments of the invention may be employed without departing from the spirit and scope of the invention as defined in the following claims.

We claim: I

1. In combination with a horizontally positioned vitreous enamel lined cylindrical vessel, a pair of brackets at each head disposed on opposite sides of the lower half of the vessel, each bracket comprising a vertical fin edge-welded to the vessel along a circumferential line at the head and a foot plate welded to the outer lower edge of said fin, and a brace plate welded to said foot plate and inclined upwardly and diagonally engagingthe cylindrical body of the vessel on a curved line and edge welded to the vessel along said line of engagement. 0

2. In combination with a horizontally positioned vitreous enamel lined cylindrical vessel, a pair of brackets at each head disposed on opposite sides 01 the lower half of the vessel, each bracket comprising a vertical fin edge-welded to the vessel along a circumferential line at the head, a foot plate welded to the outer lower edge of said iin and a gusset plate welded to said fin and foot plate, a brace plate welded to said foot plate and inclined upwardly and diagonally engaging 10 the cylindrical body or the vessel along a curved line and edge welded to the vessel along said line of engagement, and a reenforcing webedge welded to a face of said brace plate.

3. In combination with a horizontally disposed cylindrical vessel, a supporting bracket secured to the side wall thereof, and a brace extending diagonally from said bracket to engage the side wall of said vessel on a curved line, said brace being welded to said side wall along said curved line.
